Troppo Architects was established in Darwin, northern Australia, in 1981. The radical 'Troppo Style' of their houses ed in the 1980s blur edges between indoors and outdoors, formality and informality, and enclosure and openness. In this paper a corpus of ten of those houses is examined through the lens of philosopher Warwick Fox's concept of responsive cohesion. This is a unique quality of the relations between the internal components of a 'thing' and also between the 'thing' and its contexts. The houses are exemplary in demonstrating this quality of mutual and subtle response through the interactions between their form and local environmental and cultural contexts, including the idea of responsible hedonism as a principle. The research utilises original documents, site visits and interviews with stakeholders, particularly the architects and the residents. The outcomes reveal interlocking links between the dwelling, the place, the values of the architects and their clients, and the global bio-physical world. They show objectives of personal enjoyment of life and environmental responsibility could co-exist in harmony. However, the research also shows how these houses change over time depending on their location and on the attitudes of their owners. They would not work elsewhere, or for clients without a similar attitude to life and the pleasures offered by everyday living close to the variety and stimuli of the outdoors. © 2013 Cambridge University Press.

The growing interest in integrating interactive multimedia features into web applications has recently led to the creation of the W3C WebRTC and the IETF RTCWEB working groups. Such groups are jointly defining both the application programming interfaces and the underlying communication protocols for the setup and management of a reliable communication path between any pair of next-generation web browsers. While the ongoing work is focusing on peer-to-peer communication between browsers, engineers are also facing a new issue, associated with the coexistence of legacy SIPbased systems with the upcoming browserenabled architectures. We herein discuss how we tackled such an issue, by first identifying interoperability requirements and then presenting a real-world interoperability example dealing with the integration of RTCWEB clients into an existing standards-based collaboration platform. © 1979-2012 IEEE.

Over the past decade, large-scale camera networks have become increasingly prevalent in a wide range of applications, such as security and surveillance, disaster response, and environmental modeling. In many applications, bandwidth constraints, security concerns, and difficulty in storing and analyzing large amounts of data centrally at a single location necessitate the development of distributed camera network architectures. Thus, the development of distributed scene-analysis algorithms has received much attention lately. However, the performance of these algorithms often suffers because of the inability to effectively acquire the desired images, especially when the targets are dispersed over a wide field of view (FOV). In this article, we show how to develop an end-to-end framework for integrated sensing and analysis in a distributed camera network so as to maximize various scene-understanding performance criteria (e.g., tracking accuracy, best shot, and image resolution). We show how the existing work in autonomous multiagent systems can be leveraged for this purpose, more specifically, game theory-based distributed optimization algorithms for dynamic camera network reconfiguration and consensus algorithms for scene analysis. An experimental test bed for evaluating such work is described, and the comparisons against other approaches are provided. The results from a reallife camera network are also presented. © 2006 IEEE.

INES (INtelligent Educational System) is an operative prototype of an e-learning platform, which counts with functionalities of Learning Management Systems, Learning Content Management Systems, and Intelligent Tutoring Systems. To achieve these functionalities, our system includes several tools and technologies, such as: i) semantic management of users and contents; ii) an conversational agent to communicate with students in natural language; iii) BDI-based (Believes, Desires, Intentions) agents, which shape the tutoring module of the system; iv) an inference engine; and v) ontologies, to semantically model the users, their activities, and the learning contents. At the present paper we will address the intelligent tutoring module, and more specifically, its BDI-based agents. Briefly, the tasks of these agents are to recognize each student (checking his/her system credentials) and to obtain information about his/her learning progress. So, it can be able to suggest to each one specific tasks to achieve his/her particular learning objectives. The student himself/herself will decide if he/she accepts these tasks or ask for other ones. These new requested tasks can be delivered or not by the intelligent tutoring module, taking into account its decisions, which are based in several parameters related to the existing learning paths and the student's profile. © 2010 IEEE.

In this article we present Meetecho Mobile, an innovative conferencing client designed for mobile devices. Such a client provides access to conferences compliant with the most recent standard proposals currently under definition within the IETF. It allows mobile users to participate in multimedia conferences involving, besides an XMPP-based chat, both audio and video streams. The article discusses the design and implementation of the conferencing client and highlights the most notable solutions we devised in order to effectively handle a whole suite of protocols, ranging from signaling (SIP/SDP, XMPP) to real-time streaming (RTP). We also provide information about the main performance figures characterizing the client's behavior. © 2011 IEEE.
